Description

TECHNICAL FIELD

The disclosure relates to the field of communication technologies, and in particular, to a HARQ feedback method and device.

BACKGROUND

In the research of wireless communication technology, satellite communication is considered an important aspect of the future development of wireless communication technology. Satellite communication refers to the communication conducted by wireless communication equipment on the ground using satellites as relays. However, due to the long signal transmission distance in satellite communication scenarios, there is a large delay in data transmission. This large delay may lead to hybrid automatic repeat request (HARQ) delay issues, where the network device needs to wait for the terminal device to return HARQ feedback for downlink transmission before proceeding with subsequent downlink transmission. However, due to this large delay, the network device has a longer waiting time, which hinders subsequent downlink transmission.
In order to solve the problem of HARQ delay, in the related art, if a network device schedules a transport block through a scheduling instruction, the terminal device can determine whether to send HARQ feedback based on whether the HARQ process of the transport block is in a disabled state. Correspondingly, for the network device, since the HARQ process of the transport block can be in the disabled state, it can at least avoid waiting for HARQ feedback in the disabled state. However, there is still a lack of clear HARQ feedback methods in the related art for a case that the scheduling instruction schedules a plurality of transport blocks.

DETAILED DESCRIPTION

For ease of understanding, the terms involved in this disclosure are first introduced.

1. Downlink Control Information (DCI)

DCI is carried by the physical downlink control channel (PDCCH) and can include uplink and downlink resource allocation, HARQ feedback, power control, etc. PDCCH is a physical channel configured to carry downlink control information.

2. HARQ feedback

The HARQ protocol is one of the most important features in cellular communication systems. The feedback information of HARQ feedback can be HARQ acknowledge (ACK) feedback or HARQ negative acknowledgement (NACK) feedback. Using the HARQ protocol, a network device needs to wait for feedback from a terminal device before sending new data. In the case of NACK, the network device may need to resend data packets. Otherwise, the network device can send new data. This stopping and waiting process introduces inherent latency to communication protocols, which may reduce link throughput.
In order to solve the problem of HARQ delay, in the related art, if a network device schedules a transport block through a scheduling instruction, the terminal device can determine whether to send HARQ feedback based on whether the HARQ process of the transport block is in an disabled state. Correspondingly, for the network device, since the HARQ process of the transport block may be in the disabled state, it can at least avoid waiting for HARQ feedback in the disabled state. However, there is still a lack of clear HARQ feedback methods in the related art for a case that the scheduling instruction schedules a plurality of transport blocks.
In order to better understand the HARQ feedback method disclosed in embodiments of the present disclosure, the following first describes the communication system to which the embodiments are applicable.

It can be understood that the communication system described in embodiments of the present disclosure is intended to provide a clearer explanation of the technical solution of this disclosure, and does not constitute a limitation on the technical solution provided in this disclosure. Those of ordinary skill in the art will know that with the evolution of system architecture and the emergence of new business scenarios, the technical solution provided in this disclosure is also applicable to similar technical problems.
In order to clearly illustrate the HARQ feedback method of the terminal device in the aforementioned communication system when a plurality of transport blocks are scheduled based on the scheduling instruction of the network device, the HARQ feedback method and device provided in this disclosure will be described in detail below with reference to the accompanying drawings.
Please refer to Fig. 2, which is a schematic flowchart of a HARQ feedback method provided in an embodiment of the present disclosure. As shown in Fig. 2, the method is performed by a terminal device and may include, but is not limited to, the following steps.
At step 201, a scheduling instruction sent by a network device is received, in which the scheduling instruction is configured to schedule a plurality of transport blocks.
In all embodiments of the present disclosure, the plurality of transport blocks are scheduled using the same scheduling instruction.
The network device schedules the transmission of a plurality of transport blocks through the scheduling instruction, so that the terminal device can receive information carried by the plurality of transport blocks on the plurality of transmission resources scheduled by the scheduling instruction. After receiving the information carried by the plurality of transport blocks, the terminal device can determine whether HARQ feedback is needed for these a plurality of transport blocks and/or determine the HARQ information for HARQ feedback. In embodiments of the present disclosure, a plurality of refers to two or more.
For example, for the NB-IoT terminal device, the network device can schedule unicast transport blocks for a plurality of narrowband physical downlink shared channels (NPDSCH) through the narrowband physical downlink control channel (NPDCCH). In the example of scheduling unicast transport blocks for two NPDSCH channels by the network device, the scheduled transport blocks can be referred to as TB (Transport Block) 1 and TB2. The terminal device receives the information carried by the transport blocks TB1 and TB2 on the transmission resources of the transport blocks TB1 and TB2 scheduled by the scheduling instruction. After receiving the information carried by the transport blocks TB1 and TB2, the terminal device determines whether to send corresponding HARQ feedback for TB1 and TB2 respectively. The specific steps for HARQ feedback will be described in the subsequent steps, and will not be elaborated in this step.
It should be noted that the network device can send the scheduling instruction based on a DCI signaling, or send the scheduling instruction based on a high-layer signaling such as Radio Resource Control (RRC), or send the scheduling instruction based on a physical layer signaling such as Mobile edge computing (MEC) user network edge device (Customer Edge, CE), which is not limited in this embodiment.
At step 202, in response to the plurality of transport blocks including a first transport block with HARQ feedback enabled and a second transport block with HARQ feedback disabled, at least one HARQ feedback is sent to the network device, in which the at least one HARQ feedback includes HARQ feedback corresponding to the first transport block.
The network device transmits information through the first transport block and the second transport block. After the terminal device receives the information carried by the network device through the first and second transport blocks, it decodes the information carried by the first and second transport blocks respectively to determine whether the information carried by the first and second transport blocks has been correctly received.
For the first transport block, if the terminal device correctly receives the information carried by the first transport block, HARQ information of the HARQ feedback corresponding to the first transport block is ACK; if the terminal device does not correctly receive the information carried by the first transport block, HARQ information of the HARQ feedback corresponding to the first transport block is NACK. Correspondingly, the network device determines whether the terminal device has correctly received the information carried by the first transport block based on whether the HARQ information of the HARQ feedback corresponding to the first transport block sent by the terminal device is ACK or NACK.
For the second transport block, as it is a second transport block with HARQ feedback disabled, regardless of whether the terminal device correctly receives the information carried by the second transport block, the terminal device does not need to send HARQ feedback corresponding to the second transport block to the network device. That is, in step 202, in response to a plurality of transport blocks including a first transport block with HARQ feedback enabled and a second transport block with HARQ feedback disabled, at least one HARQ feedback is sent to the network device, in which the at least one HARQ feedback includes the HARQ feedback corresponding to the first transport block and does not include the HARQ feedback corresponding to the second transport block.
As shown in Fig. 3, the schematic diagram depicts the terminal device receiving TB1 transmission and TB2 transmission based on the downlink channel (DL) when two transport blocks are scheduled with the same scheduling instruction. The transport block TB1 used for TB1 transmission is the first transport block with HARQ feedback enabled, and the transport block TB2 used for TB2 transmission is the second transport block with HARQ feedback disabled. As shown in Fig. 3, the terminal device can transmit HARQ feedback for the transport block TB1 in the uplink channel (UL), but not transmit HARQ feedback for the transport block TB2. Correspondingly, after transmitting TB1 and TB2 on the downlink channel, the network device only needs to wait to receive HARQ feedback from the terminal device for transport block TB1, but does not need to wait for HARQ feedback for transport block TB2, in order to proceed with subsequent transmissions, thereby reducing the transmission delay caused by waiting to a certain extent.
By implementing this embodiment of the present disclosure, after receiving information carried by a plurality of transport blocks scheduled by the same scheduling instruction, the terminal device can send only corresponding HARQ feedback for the first transport blocks with HARQ feedback enabled, in the plurality of transport blocks, to the network device. In this way, the network device can avoid waiting for all HARQ feedback corresponding to a plurality of transport blocks to be received before proceeding with subsequent transmissions, which is beneficial for reducing the transmission delay caused by waiting for HARQ feedback to a certain extent.
Please refer to Fig. 4, which is a schematic flowchart of another HARQ feedback method provided in an embodiment of the present disclosure. As shown in Fig. 4, the method is performed by a terminal device, and the method may include, but is not limited to, the following steps.
At step 401, a scheduling instruction sent by a network device is received, in which the scheduling instruction is configured to schedule transmission of a plurality of transport blocks.
Please refer to the relevant descriptions in the previous embodiments, which will not be repeated in this embodiment.
At step 402, in response to the plurality of transport blocks including a first transport block with HARQ feedback enabled and a second transport block with HARQ feedback disabled, at least one HARQ feedback is sent to the network device, in which the at least one HARQ feedback includes HARQ feedback corresponding to the first transport block and HARQ feedback corresponding to the second transport block.
The network device transmits information through the first transport block and the second transport block. After the terminal device receives the information carried by the network device through the first and second transport blocks, it decodes the information carried by the first and second transport blocks respectively to determine whether the information carried by the first and second transport blocks has been correctly received.
For the first transport block, if the terminal device correctly receives the information carried by the first transport block, HARQ information of the HARQ feedback corresponding to the first transport block is ACK; if the terminal device does not correctly receive the information carried by the first transport block, HARQ information of the HARQ feedback corresponding to the first transport block is NACK. Correspondingly, the network device determines whether the terminal device has correctly received the information carried by the first transport block based on whether the HARQ information of the HARQ feedback corresponding to the first transport block sent by the terminal device is ACK or NACK.
For the second transport block, as the first possible implementation, the HARQ feedback corresponding to the second transport block contains HARQ information configured to determine whether the information carried by the second transport block has been successfully received. If the terminal device correctly receives the information carried by the second transport block, the HARQ feedback corresponding to the second transport block contains HARQ information as ACK; if the terminal device does not correctly receive the information carried by the second transport block, the HARQ feedback corresponding to the second transport block contains HARQ information as NACK. Correspondingly, the network device determines whether the terminal device has correctly received the information carried by the second transport block based on whether the HARQ information of the HARQ feedback corresponding to the second transport block sent by the terminal device is ACK or NACK. The network device can wait for HARQ feedback for the second transport block, or can proceed with subsequent transmission without waiting for HARQ feedback for the second transport block, thereby reducing the transmission delay caused by waiting to a certain extent.
For the second transport block, as the second possible implementation, the HARQ information in the HARQ feedback corresponding to the second transport block is the default value. That is to say, regardless of whether the terminal device correctly receives the information carried by the second transport block, the HARQ feedback corresponding to the second transport block contains the same default value of HARQ information, which can be exemplified by ACK or NACK. Correspondingly, the network device cannot determine whether the terminal device has correctly received the information carried by the second transport block based on the HARQ information of the HARQ feedback corresponding to the second transport block sent by the terminal device. Therefore, the network device can proceed with subsequent transmissions without waiting for HARQ feedback for the second transport block, thereby reducing the transmission delay caused by waiting to a certain extent.
As shown in Fig. 5, the schematic diagram depicts the terminal device receiving TB1 transmission and TB2 transmission based on the downlink channel (DL) when two transport blocks are scheduled with the same scheduling instruction. The transport block TB1 used for TB1 transmission is the first transport block with HARQ feedback enabled, and the transport block TB2 used for TB2 transmission is the second transport block with HARQ feedback disabled. As shown in Fig. 5, the terminal device can transmit HARQ feedback for transport block TB1 and HARQ feedback for transport block TB2 in the uplink channel (UL). Correspondingly, the network device needs to wait to receive HARQ feedback for the transport block TB1 sent by the terminal device after transmitting TB1 and TB2 based on the downlink channel. After receiving the HARQ feedback for transport block TB1, the network device can wait for the HARQ feedback for transport block TB2, or can proceed with subsequent transmission without waiting for the HARQ feedback for transport block TB2, thereby reducing the transmission delay caused by waiting to a certain extent.
By implementing this embodiment of the present disclosure, after receiving information carried by a plurality of transport blocks scheduled by the same scheduling instruction, the terminal device can send corresponding HARQ feedback for the first transport block with HARQ feedback enabled in the plurality of transport blocks to the network device. The network device can wait for HARQ feedback for the second transport block, or can proceed with subsequent transmissions without waiting for HARQ feedback for the second transport block. In this way, the network device can avoid waiting for all HARQ feedback corresponding to a plurality of transport blocks to be received before proceeding with subsequent transmissions, which is beneficial for reducing the transmission delay caused by waiting for HARQ feedback to a certain extent.
Please refer to Fig. 6, which is a schematic flowchart of another HARQ feedback method provided in an embodiment of the present disclosure. As shown in Fig. 6, the method is performed by a terminal device, and the method may include, but is not limited to, the following steps.
At step 601, a scheduling instruction sent by a network device is received, in which the scheduling instruction is configured to schedule transmission of a plurality of transport blocks.
Please refer to the relevant descriptions in the previous embodiments, which will not be repeated in this embodiment.
At step 602, in response to the plurality of transport blocks including only second transport blocks with HARQ feedback disabled, HARQ feedback corresponding to any of the second transport blocks is not sent to the network device.
The network device transmits information through the second transport blocks. After receiving the information carried by the network device through the second transport blocks, the terminal device decodes the information carried by each second transport block separately to determine whether the information carried by each second transport block has been correctly received. For each second transport block, regardless of whether the terminal device correctly receives the information carried by each second transport block, the terminal device does not send any HARQ feedback corresponding to any of the second transport blocks to the network device. Therefore, the network device can perform subsequent transmissions without waiting for HARQ feedback for the second transport block, thereby reducing the transmission delay caused by waiting to a certain extent.
As shown in Fig. 7, the schematic diagram depicts the terminal device receiving TB1 transmission and TB2 transmission based on the downlink channel (DL) when two transport blocks are scheduled with the same scheduling instruction. The transport block TB1 used for TB1 transmission and the transport block TB2 used for TB2 transmission are both second transport blocks with HARQ feedback disabled. As shown in Fig. 7, the terminal device can not send any HARQ feedback in the uplink channel (UL), that is, not send HARQ feedback for transport block TB1, and not send HARQ feedback for transport block TB2. Correspondingly, after transmitting the transport block TB1 and the transport block TB2 based on the downlink channel, the network device can proceed with subsequent transmissions without waiting to receive HARQ feedback sent by the terminal devices for transport blocks TB1 and TB2, thereby reducing the transmission delay caused by waiting to a certain extent.
By implementing this embodiment of the present disclosure, if the terminal device receives information carried by a plurality of transport blocks scheduled by the same scheduling instruction and the plurality of transport blocks include only the second transport blocks with HARQ feedback disabled, it will not send any HARQ feedback corresponding to any of the second transport blocks to the network device. Correspondingly, the network device can proceed with subsequent transmissions without waiting for the HARQ feedback corresponding to all transport blocks in a plurality of transport blocks to be received. In this way, the network device can avoid waiting for all HARQ feedback corresponding to a plurality of transport blocks to be received before proceeding with subsequent transmissions, which is beneficial for reducing the transmission delay caused by waiting for HARQ feedback to a certain extent.
Please refer to Fig. 8, which is a schematic flowchart of another HARQ feedback method provided in an embodiment of the present disclosure. As shown in Fig. 8, the method is performed by a terminal device, and the method may include, but is not limited to, the following steps.
At step 801, a scheduling instruction sent by a network device is received, in which the scheduling instruction is configured to schedule transmission of a plurality of transport blocks.
Please refer to the relevant descriptions in the previous embodiments, which will not be repeated in this embodiment.
At step 802, in response to the plurality of transport blocks including only first transport blocks with HARQ feedback enabled, HARQ feedback corresponding to at least one of the first transport blocks is sent to the network device.
The network device transmits information through the first transport blocks. After receiving the information carried by the network device through the first transport blocks, the terminal device decodes the information carried by each first transport block to determine whether the information carried by each first transport block has been correctly received.
For each first transport block, the terminal device can send only the HARQ feedback corresponding to one of the plurality of first transport blocks to the network device, or it can also send the corresponding HARQ feedback for each first transport block to the network device.
As a possible implementation, the terminal device only sends HARQ feedback corresponding to one of the first transport blocks to the network device. The HARQ information of the HARQ feedback sent by the terminal device can be determined based on whether the information carried by a plurality of first transport blocks has been correctly received. For example, in the case where the information carried by a plurality of first transport blocks has been correctly received, the HARQ feedback information of the HARQ feedback sent by the terminal device to the network can be ACK; in the case where at least one of the information carried by a plurality of first transport blocks is not received correctly, the HARQ feedback information of the HARQ feedback sent by the terminal device to the network can be NACK.
As another possible implementation, the terminal device sends HARQ feedback corresponding to each first transport block in the plurality of first transport blocks to the network device, and the HARQ information of the HARQ feedback sent by the terminal device can be determined based on whether the information carried by the corresponding first transport block has been correctly received.
As shown in Fig. 9, the schematic diagram depicts the terminal device receiving TB1 transmission and TB2 transmission based on the downlink channel (DL) when two transport blocks are scheduled with the same scheduling instruction. The transport block TB1 used for TB1 transmission and the transport block TB2 used for TB2 transmission are both the first transport blocks with HARQ feedback enabled. The terminal device can send HARQ feedback for at least one transport block in the uplink channel (UL), for example, as shown in Fig. 9, HARQ feedback can be sent for both transport blocks TB1 and TB2. Correspondingly, after transmitting the transport block TB1 and the transport block TB2 based on the downlink channel, the network device can wait to receive HARQ feedback for at least one of the transport blocks TB1 and TB2, and can proceed with subsequent transmission without waiting to receive HARQ feedback sent by the terminal device for the remaining of the transport blocks TB1 and TB2, thereby reducing the transmission delay caused by waiting to a certain extent.
It should be noted that those skilled in the art can understand that the network device can also wait to receive HARQ feedback for all transport blocks TB1 and TB2 before proceeding with subsequent transmissions, which is not limited in this embodiment.
By implementing this embodiment of the present disclosure, after receiving information carried by a plurality of transport blocks scheduled by the same scheduling instruction, if only the first transport blocks with HARQ feedback enabled are included in the plurality of transport blocks, the terminal device sends HARQ feedback corresponding to at least one of the first transport blocks to the network device. Correspondingly, after receiving HARQ feedback corresponding to the at least one transport block in the plurality of transport blocks, the network device can proceed with subsequent transmissions. In this way, it is possible to avoid the network device having to wait for all HARQ feedback corresponding to a plurality of transport blocks to be received before proceeding with subsequent transmissions, which is beneficial for reducing the transmission delay caused by waiting for HARQ feedback to a certain extent.
Please refer to Fig. 10, which is a schematic flowchart of another HARQ feedback method provided in an embodiment of the present disclosure. As shown in Fig. 10, the method is performed by a terminal device, and the method may include, but is not limited to, the following steps.
At step 1001, indication information sent by a network device is received, in which the indication information is configured to determine whether the at least one transport block in the plurality of transport blocks is the first transport block with HARQ feedback enabled, or the second transport block with HARQ feedback disabled.
In embodiments of the present disclosure, in a possible implementation, it is possible to indicate whether each transport block enables HARQ feedback or not. In another possible implementation, the transport block can be defaulted to enable HARQ feedback, and the network device indicates the transport block with HARQ feedback disabled. In yet another possible implementation, the transport block can be defaulted to be a transport block with HARQ feedback disabled, and the network device indicates the transport block with HARQ feedback enabled. The network device sends the indication information based on high-layer signaling such as RRC, or based on physical layer signaling such as MEC CE, or based on DCI signaling, which is not limited in this embodiment.
As a possible implementation, this indication information is configured to indicate a plurality of available transport blocks between the network devices and the terminal device. The signaling configured to send the indication information also carries an indication field, which can be newly added or reused from an existing indication field. The terminal device determines whether at least one transport block among a plurality of transport blocks is the first transport block with HARQ feedback enabled or the second transport block with HARQ feedback disabled based on the indication field.
The network device uses the indication information to enable the terminal device to determine the available a plurality of transport blocks between the network device and the terminal device, and whether the plurality of transport blocks are the first transport blocks or the second transport blocks, so that the network device can select at least some transport blocks from the available a plurality of transport blocks for scheduling through the scheduling instruction.
Technicians in this field may know that the indication information configured to indicate whether a plurality of transport blocks are the first transport block or the second transport block can be sent through a plurality of signaling, for example, each signaling indicates whether at least one transport block is the first transport block or the second transport block. The indication information can also be sent through a signaling. For example, when the indication information is sent through a signaling, it indicates whether each of the plurality of transport blocks is the first transport block or the second transport block respectively.
At step 1002, a scheduling instruction sent by the network device is received, in which the scheduling instruction is configured to schedule transmission of a plurality of transport blocks.
At step 1003, in response to the plurality of transport blocks including a first transport block with HARQ feedback enabled and a second transport block with HARQ feedback disabled, at least one HARQ feedback is sent to the network device, in which the at least one HARQ feedback includes HARQ feedback corresponding to the first transport block.
Steps 1002 and 1003 are described in detail in the previous embodiments, and will not be repeated in this embodiment.
By implementing this embodiment of the present disclosure, after receiving information carried by a plurality of transport blocks scheduled by the same scheduling instruction, the terminal device can send corresponding HARQ feedback to the network device only for the first transport blocks with HARQ feedback enabled among the plurality of transport blocks. In this way, the network device can avoid waiting for all HARQ feedback corresponding to a plurality of transport blocks to be received before proceeding with subsequent transmissions, which is beneficial for reducing the transmission delay caused by waiting for HARQ feedback to a certain extent.
Please refer to Fig. 11, which is a schematic flowchart of another HARQ feedback method provided in an embodiment of the present disclosure. As shown in Fig. 10, the method is performed by a terminal device, and the method may include, but is not limited to, the following steps.
At step 1101, it is determined whether at least one transport block in the plurality of transport blocks is the first transport block or the second transport block based on configuration information specified in a protocol.
As a possible implementation, the configuration information specified in the protocol specifies a plurality of transport blocks available between the network device and the terminal device, and whether the plurality of transport blocks are the first or second transport blocks, in order for the network device to select at least some transport blocks from the specified available a plurality of transport blocks for scheduling through the scheduling instruction.
At step 1102, a scheduling instruction sent by the network device is received, in which the scheduling instruction is configured to schedule transmission of a plurality of transport blocks.
At step 1103, in response to the plurality of transport blocks including a first transport block with HARQ feedback enabled and a second transport block with HARQ feedback disabled, at least one HARQ feedback is sent to the network device, in which the at least one HARQ feedback includes HARQ feedback corresponding to the first transport block.
Steps 1102 and 1103 are described in detail in the previous embodiments, and will not be repeated in this embodiment.
By implementing this embodiment of the present disclosure, after receiving information carried by a plurality of transport blocks scheduled by the same scheduling instruction, the terminal device can send corresponding HARQ feedback to the network device only for the first transport blocks with HARQ feedback enabled among the plurality of transport blocks. In this way, the network device can avoid waiting for all HARQ feedback corresponding to a plurality of transport blocks to be received before proceeding with subsequent transmissions, which is beneficial for reducing the transmission delay caused by waiting for HARQ feedback to a certain extent.
Technicians in this field can understand that the aforementioned a plurality of embodiments executed by the terminal device can be implemented independently or combined in any way, which is not limited in the embodiments of the present disclosure.
Please refer to Fig. 12, which is a schematic flowchart of another HARQ feedback method provided in an embodiment of the present disclosure. As shown in Fig. 12, the method is performed by a network device and may include, but is not limited to, the following steps.
At step 1201, a scheduling instruction is sent to a terminal device, in which the scheduling instruction is configured to schedule a plurality of transport blocks.
The network device can send the scheduling instruction to the terminal device. The scheduling instruction is configured to schedule the transmission of a plurality of transport blocks. It can be understood that since the network device can schedule the transmission of a plurality of transport blocks in the scheduling instruction, the terminal device can correspondingly receive the information carried by the plurality of transport blocks on the plurality of transmission resources scheduled by the scheduling instruction, and then after the terminal device receives the information carried by the plurality of transport blocks, the terminal device can determine whether HARQ feedback is required for these a plurality of transport blocks, and/or determine the HARQ information of the HARQ feedback.
It should be noted that the network device can send the scheduling instruction based on a DCI signaling, or send the scheduling instruction based on a high-layer signaling such as RRC, or send the scheduling instruction based on a physical layer signaling such as MEC CE, which is not limited in this embodiment.
At step 1202, in response to the plurality of transport blocks including a first transport block with HARQ feedback enabled and a second transport block with HARQ feedback disabled, the network device waits to receive at least one HARQ feedback sent by the terminal device, in which the at least one HARQ feedback includes HARQ feedback corresponding to the first transport block.
The network device transmits information through the first transport block and the second transport block. After the terminal device receives the information carried by the network device through the first and second transport blocks, it decodes the information carried by the first and second transport blocks respectively to determine whether the information carried by the first and second transport blocks has been correctly received, and sends HARQ feedback to the network device, so that the network device can continue subsequent transmission after receiving the HARQ feedback sent by the terminal device.
For the first transport block, the terminal device can send the HARQ feedback information corresponding to the first transport block to the network device based on whether the information carried by the first transport block and the information carried by the second transport block have been correctly received. Specifically, if the terminal device correctly receives the information carried by the first transport block, HARQ information of the HARQ feedback corresponding to the first transport block is ACK; if the terminal device does not correctly receive the information carried by the first transport block, HARQ information of the HARQ feedback corresponding to the first transport block is NACK. Correspondingly, the network device can wait to receive the HARQ feedback information corresponding to the first transport block sent by the terminal device, and determine whether the terminal device has correctly received the information carried by the first transport block based on whether the HARQ information is ACK or NACK.
For the second transport block, as it is a second transport block with HARQ feedback disabled, regardless of whether the terminal device correctly receives the information carried by the second transport block, the terminal device does not need to send HARQ feedback corresponding to the second transport block to the network device. Correspondingly, the network device does not need to wait to receive the HARQ feedback corresponding to the second transport block sent by the terminal device. That is, in step 1202, in response to a plurality of transport blocks including a first transport block with HARQ feedback enabled and a second transport block with HARQ feedback disabled, waiting to receive at least one HARQ feedback sent by the terminal device, in which at least one HARQ feedback includes the HARQ feedback corresponding to the first transport block and does not include the HARQ feedback corresponding to the second transport block.
By implementing this embodiment of the present disclosure, the network device can wait to receive the corresponding HARQ feedback sent by the terminal device, for only the first transport blocks with HARQ feedback enabled among the plurality of transport blocks after sending the information carried by the plurality of transport blocks scheduled by the scheduling instruction to the terminal device. In this way, the network device can avoid waiting for all HARQ feedback corresponding to a plurality of transport blocks to be received before proceeding with subsequent transmissions, which is beneficial for reducing the transmission delay caused by waiting for HARQ feedback to a certain extent.
Please refer to Fig. 13, which is a schematic flowchart of another HARQ feedback method provided in an embodiment of the present disclosure. As shown in Fig. 13, the method is performed by a network device and may include, but is not limited to, the following steps.
At step 1301, a scheduling instruction is sent to a terminal device, in which the scheduling instruction is configured to schedule a plurality of transport blocks.
Please refer to the relevant descriptions in the previous embodiments, which will not be repeated in this embodiment.
At step 1302, in response to the plurality of transport blocks including a first transport block with HARQ feedback enabled and a second transport block with HARQ feedback disabled, the network device waits to receive at least one HARQ feedback sent by the terminal device, in which the at least one HARQ feedback includes HARQ feedback corresponding to the first transport block and HARQ feedback corresponding to the second transport block.
The network device transmits information through the first transport block and the second transport block. After the terminal device receives the information carried by the network device through the first and second transport blocks, it decodes the information carried by the first and second transport blocks respectively to determine whether the information carried by the first and second transport blocks has been correctly received, and sends HARQ feedback to the network device, so that the network device can proceed with subsequent transmissions after receiving the HARQ feedback sent by the terminal device.
For the first transport block, the terminal device can send the HARQ feedback information corresponding to the first transport block to the network device based on whether the information carried by the first transport block and the information carried by the second transport block have been correctly received. Specifically, if the terminal device correctly receives the information carried by the first transport block, HARQ information of the HARQ feedback corresponding to the first transport block is ACK; if the terminal device does not correctly receive the information carried by the first transport block, HARQ information of the HARQ feedback corresponding to the first transport block is NACK. Correspondingly, the network device can wait to receive the HARQ feedback information corresponding to the first transport block sent by the terminal device, and determine whether the terminal device has correctly received the information carried by the first transport block based on whether the HARQ information is ACK or NACK.
For the second transport block, as the first possible implementation, the HARQ feedback corresponding to the second transport block contains HARQ information configured to determine whether the information carried by the second transport block has been successfully received. If the terminal device correctly receives the information carried by the second transport block, the HARQ feedback corresponding to the second transport block contains HARQ information as ACK; if the terminal device does not correctly receive the information carried by the second transport block, the HARQ feedback corresponding to the second transport block contains HARQ information as NACK. Correspondingly, the network device determines whether the terminal device has correctly received the information carried by the second transport block based on the HARQ information of the HARQ feedback corresponding to the second transport block sent by the terminal device, which is ACK or NACK. It should be noted that the network device can wait for HARQ feedback for the second transport block, or can proceed with subsequent transmissions without waiting for HARQ feedback for the second transport block, thereby reducing the transmission delay caused by waiting to a certain extent.
For the second transport block, as a second possible implementation, the HARQ information in the HARQ feedback corresponding to the second transport block is the default value. That is to say, regardless of whether the terminal device correctly receives the information carried by the second transport block, the HARQ feedback corresponding to the second transport block contains the same default value of HARQ information, which can be exemplified by ACK or NACK. Correspondingly, the network device cannot determine whether the terminal device has correctly received the information carried by the second transport block based on the HARQ feedback corresponding to the second transport block sent by the terminal device. Therefore, the network device can proceed with subsequent transmissions without waiting for HARQ feedback for the second transport block, thereby reducing the transmission delay caused by waiting to a certain extent.
By implementing this embodiment of the present disclosure, after the network device sends the information carried by the plurality of transport blocks scheduled by the scheduling instruction to the terminal device, the network device can wait to receive the corresponding HARQ feedback sent by the terminal device, for only the first transport blocks with HARQ feedback enabled among the plurality of transport blocks. The network device can wait for HARQ feedback for the second transport block, or can proceed with subsequent transmissions without waiting for HARQ feedback for the second transport block. In this way, the network device can avoid waiting for all HARQ feedback corresponding to a plurality of transport blocks to be received before proceeding with subsequent transmissions, which is beneficial for reducing the transmission delay caused by waiting for HARQ feedback to a certain extent.
Please refer to Fig. 14, which is a schematic flowchart of another HARQ feedback method provided in an embodiment of the present disclosure. As shown in Fig. 14, the method is performed by a network device and may include, but is not limited to, the following steps.
At step 1401, a scheduling instruction is sent to a terminal device, in which the scheduling instruction is configured to schedule a plurality of transport blocks.
Please refer to the relevant descriptions in the previous embodiments, which will not be repeated in this embodiment.
At step 1402, in response to the plurality of transport blocks including only second transport blocks with HARQ feedback disabled, the network device does not wait for the terminal device to send HARQ feedback corresponding to any of the second transport blocks.
The network device transmits information through the second transport blocks. After receiving the information carried by the network device through the second transport blocks, the terminal device will decode the information carried by each second transport block separately to determine whether the information carried by each second transport block has been correctly received. For each second transport block, regardless of whether the terminal device correctly receives the information carried by each second transport block, the terminal device does not send any HARQ feedback corresponding to any of the second transport blocks to the network device. Therefore, the network device can perform subsequent transmissions without waiting for HARQ feedback for the second transport block, thereby reducing the transmission delay caused by waiting to a certain extent.
By implementing this embodiment of the present disclosure, after the network device sends the information carried by the plurality of transport blocks scheduled by the scheduling instruction to the terminal device, if the plurality of transport blocks only include the second transport blocks with HARQ feedback disabled, there is no need to wait to receive the HARQ feedback corresponding to any of the second transport blocks sent by the terminal device. That is to say, the network device does not need to wait for the HARQ feedback corresponding to all transport blocks in a plurality of transport blocks to be received before proceeding with subsequent transmissions. In this way, the network device can avoid waiting for all HARQ feedback corresponding to a plurality of transport blocks to be received before proceeding with subsequent transmissions, which is beneficial for reducing the transmission delay caused by waiting for HARQ feedback to a certain extent.
Please refer to Fig. 15, which is a schematic flowchart of another HARQ feedback method provided in an embodiment of the present disclosure. As shown in Fig. 15, the method is performed by a network device and may include, but is not limited to, the following steps.
At step 1501, a scheduling instruction is sent to a terminal device, in which the scheduling instruction is configured to schedule a plurality of transport blocks.
Please refer to the relevant descriptions in the previous embodiments, which will not be repeated in this embodiment.
At step 1502, in response to the plurality of transport blocks including only first transport blocks with HARQ feedback enabled, the network device waits to receive HARQ feedback corresponding to at least one of the first transport blocks sent by the terminal device.
The network device transmits information through the first transport blocks. After receiving the information carried by the network device through the first transport blocks, the terminal device will decode the information carried by each first transport block separately to determine whether the information carried by each first transport block is correctly received, and send HARQ feedback corresponding to at least one of the first transport blocks to the network device, so that the network device can continue the subsequent transmission after receiving the HARQ feedback corresponding to the at least one transport block in the plurality of transport blocks.
For each first transport block, the terminal device may only send HARQ feedback corresponding to one of the first transport blocks to the network device, or may also send corresponding HARQ feedback to the network device for each first transport block.
As a possible implementation, the terminal device only sends HARQ feedback corresponding to one of the first transport blocks to the network device, so that the network device can wait to receive the HARQ feedback corresponding to the one first transport block sent by the terminal device. Optionally, the HARQ information of the HARQ feedback sent by the terminal device can be determined based on whether the information carried by a plurality of first transport blocks has been correctly received. For example, in the case where the information carried by a plurality of first transport blocks has been correctly received, the HARQ information of the HARQ feedback sent by the terminal device to the network can be ACK; in the case where the information carried by at least one of the plurality of first transport blocks is not received correctly, the HARQ information of the HARQ feedback sent by the terminal device to the network can be NACK.
As another possible implementation, the terminal device sends HARQ feedback for each first transport block in a plurality of first transport blocks to the network device, so that the network device can wait to receive the HARQ feedback for each first transport block sent by the terminal device. Optionally, the HARQ information of HARQ feedback sent by the terminal device may be determined based on whether the information carried by the corresponding first transport block has been correctly received.
By implementing this embodiment of the present disclosure, the network device waits to receive the HARQ feedback corresponding to the at least one of the first transport blocks sent by the terminal device if only the first transport blocks with HARQ feedback enabled are included in the plurality of transport blocks, after sending the information carried by the plurality of transport blocks scheduled by the scheduling instruction to the terminal device. That is to say, after receiving HARQ feedback corresponding to the at least one transport block in the plurality of transport blocks, the network device can proceed with subsequent transmissions. In this way, it is possible to avoid the network device having to wait for all HARQ feedback corresponding to a plurality of transport blocks to be received before proceeding with subsequent transmissions, which is beneficial for reducing the transmission delay caused by waiting for HARQ feedback to a certain extent.
Please refer to Fig. 16, which is a schematic flowchart of another HARQ feedback method provided in an embodiment of the present disclosure. As shown in Fig. 16, the method is performed by a network device, and the method may include, but is not limited to, the following steps.
At step 1601, indication information is sent to a terminal device, in which the indication information is configured to determine whether the at least one transport block in the plurality of transport blocks is the first transport block, or the second transport block.
In embodiments of the present disclosure, in a possible implementation, it is possible to indicate whether each transport block enables HARQ feedback or not. The network device sends the indication information based on high-layer signaling such as RRC, or based on physical layer signaling such as MEC CE, or based on DCI signaling, which is not limited in this embodiment.
As a possible implementation, this indication information is configured to indicate a plurality of available transport blocks between the network devices and the terminal device. The signaling configured to send the indication information also carries an indication field, which can be newly added or reused from an existing indication field. The terminal device determines whether at least one transport block among a plurality of transport blocks is the first transport block with HARQ feedback enabled or the second transport block with HARQ feedback disabled based on the indication field.
The network device uses the indication information to enable the terminal device to determine the available a plurality of transport blocks between the network device and the terminal device, and whether the plurality of transport blocks are the first transport blocks or the second transport blocks, so that the network device can select at least some transport blocks from the available a plurality of transport blocks for scheduling through the scheduling instruction.
Technicians in this field may know that the indication information configured to indicate whether a plurality of transport blocks are the first transport blocks or the second transport blocks can be sent through a plurality of signaling, for example, each signaling indicates whether at least one transport block is the first transport block or the second transport block. The indication information can also be sent through a signaling. For example, when the indication information is sent through a signaling, it indicates whether each of the plurality of transport blocks is the first transport block or the second transport block respectively.
At step 1602, a scheduling instruction is sent to the terminal device, in which the scheduling instruction is configured to schedule a plurality of transport blocks.
At step 1603, in response to the plurality of transport blocks including a first transport block with HARQ feedback enabled and a second transport block with HARQ feedback disabled, the network device waits to receive at least one HARQ feedback sent by the terminal device, in which the at least one HARQ feedback includes HARQ feedback corresponding to the first transport block.
Steps 1602 and 1603 are described in detail in the previous embodiments, and will not be repeated in this embodiment.
By implementing this embodiment of the present disclosure, the network device can wait to receive the corresponding HARQ feedback sent by the terminal device, for only the first transport blocks with HARQ feedback enabled among the plurality of transport blocks after sending the information carried by the plurality of transport blocks scheduled by the scheduling instruction to the terminal device. In this way, the network device can avoid waiting for all HARQ feedback corresponding to the plurality of transport blocks to be received before proceeding with subsequent transmissions, which is beneficial for reducing the transmission delay caused by waiting for HARQ feedback to a certain extent.
